Paunonzwa 'zvakakosha zvekukanda simbi', mabhuku mazhinji anosvetukira akananga kudhayagiramu inoyerera: pateni, mold, durura, kutonhorera, kupedza. Izvozvo hazvina kuipa, asi zvakafanana nokutsanangura kutyaira nokunyora zvikamu zvemotokari. Zvinhu zvinokosha chaizvo zvinogara mumakaha ari pakati pematanho iwayo—kupisa kwemvura kuri pamusoro peladhi, kutinhira kwesimbi iri kuzadza chakuvhe, manzwire anoita chakuvhe pazvinenge zvakakodzera. Ndakaona mainjiniya akawanda achangobuda pachikoro pamuenzaniso weCAD, vachikanganwa kuti simbi ine kuda kwayo. Ndiyo yekutanga, uye pamwe yakakura, pfungwa dzisiridzo: kukanda haisi nzira yekugadzira chete; inhaurirano nefizikisi.
Iyo Core Dance: Pateni, Mold, uye Metal
Ngatitange nemuenzaniso. Ndiko pekutangira, asi dhizaini yaro ndipo paunohwina kana kurasikirwa nebasa. Draft angles haingori nhamba mubhuku rekushandisa; hafu-degree inogona kureva mutsauko pakati pemucheka wakachena uye mold yakaparadzwa. Takadzidza izvi nenzira yakaoma pabasa rekutanga repombi yepombi, tichishandisa resin patani. Dhizaini yacho yaitaridzika zvakanaka pachiratidziri, asi isu hatina kuverengera kuwedzera kwekupisa kweresin pasi pekupisa kwakanyanya kweiyo. shell mold casting process. Zvakaguma nei? Yakanaka mold ine hutsinye hwemadimensional accuracy. Chikamu chaive chikara. Kukundikana ikoko kwakandidzidzisa zvakawanda nezve zvakakosha zvekukanda simbi kupfuura chero bhuku rekuverenga: zvese zviri mucheni, kubva patani kusvika kune yekupedzisira simbi, inowedzera uye zvibvumirano. Unofanira kuvaziva vose.
Izvo zvinondiunza kuforomas. Kushop kwedu, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tinotsamira zvakanyanya pagoko uye kuisa mari. Sarudzo haina kungopokana. Kune yakakwirira-vhoriyamu, iri nyore geometries mune zvinhu zvakaita simbi yakakandwa kana kabhoni simbi, shell molding inoshanda zvinoshamisa. Iyo silica jecha rakaputirwa ne phenolic resin rinokupa iwe mold ine yakanakisa kupedzisa kwepamusoro uye inogoneka kupera. Asi hunyengeri hwakakosha huri mukurapa. Iyo mold inoda nguva yakakwana muchoto. Yakanyanya kudiki, uye haina kusimba, ichiisa njodzi yekumhanya-kunze panguva yekudira. Yakawandisa, uye inova brittle, zvinogona kukonzera inclusions mukukanda. Iwe unodzidza kuitonga nemuvara uye kunhuwa-yakanyatsojeka, inonhuhwirira zvishoma yeresin yakarapwa. Haisi mune chero bhuku rekushandisa.
Investment casting, kana kurasika-wax, imhuka yakasiyana. Ndezvezvinhu zvakaomarara — turbine blades, mavharuvhu akaoma kunzwisisa. Chakakosha apa kutonga, kudzora kwakazara, pamusoro pega rega receramic shell. Kapupu kadiki kana nzvimbo isina kusimba mubhachi rechitatu icharatidza sefin kana blister pachikamu chekupedzisira chesimbi isina tsvina. Isu tinoishandisa zvakanyanya kubasa redu nema alloys akakosha, senge nickel-based. Iko kupisa kwekutyisa kupikisa kweganda receramic kunofanirwa kunyatsoenderana nekudurura tembiricha yeaya superalloys. Ita zvisizvo, uye goko rinotsemuka, simbi inodonhedza, uye une tsvina inodhura, ine ngozi. Iyo yakakwira-stakes maitiro apo izvo zvakakosha ndezvekushivirira uye kunyatso dzokorora.
Kudurura: Apo Dzidziso Inosangana Nepasi
Ino ndiyo nguva yechokwadi. Kuronga kwese kunoperera pano. The zvakakosha zvekukanda simbi panguva yekudira ndeye thermodynamics uye fluid dynamics, asi iwe hausi kugadzirisa equations; uri kuita sarudzo dzepakati. Kupisa kwesimbi kunokosha. Kune ductile iron, tinovavarira kusvika °C. Asi iyo haisi nhamba yakatarwa. Kana zviumbwa zvichitonhora uye zvakanyorova pazuva rine hunyoro, unogona kuenda kunopisa kudzivirira kutonhora kusati kwasvika muzvikamu zvitete. Iwe unotarisa simbi inoyerera ichibva kune ladle-inofanira kunge yakadzikama, inopenya rukova, kwete splatter. Kudururwa kwemhirizhonga kunopinza mweya nemaokisi, zvichikonzera kukanganisa.
Risers uye gating masisitimu ndiwo magamba asina kuimbwa. Haisi mikoto yesimbi chete; ivo vanomanikidza uye hurongwa hwekudyisa. Ndinoyeuka basa regiya rine mativi makobvu risina kuvharwa nesimbi. Isu takaisa riser zvichienderana neyakajairwa kuverenga. Kukanda kwakasimba, uye kwaitaridzika zvakakwana. Kusvikira machina. Mugodhi wakakura wakavanzwa muwebhu chaimo. Sirimu yacho yakanga yaoma nechando pamberi penzvimbo yakakora, saka yaisakwanisa kuidya. The basic takapotsa? Solidification modelling haisi yehuwandu chete; zviri maererano negwara uye nguva. Isu ikozvino tinoshandisa simulation software segwara, asi isu tichiri kuyambuka-kutarisa nemitemo yekare yechigunwe-sekuita chokwadi chekusimuka kwehuremu hwekupisa hwakakura zvakanyanya kupfuura chikamu chairi kudya.
Material is everything (Uye Hapana)
Vanhu vanowanzofunga kuti kusarudza chinhu ndicho danho rekutanga. Dzimwe nguva ndizvo, asi kazhinji, dhizaini inoraira, uye iwe unofanirwa kuita kuti ishande. Tinobata zvese kubva kune zvakajairika simbi yakakandwa kune exotic cobalt-based alloys. Chakakosha nemidziyo kunzwisisa hunhu hwavo. Grey iron inodurura zvakanaka, inoregerera kumushini, asi inovenga kukanganisa. Ductile iron, ine nodular graphite yayo, yakasimba asi inowanzoitika kune shrinkage nyaya kana isina kubatwa nemazvo muladle.
Simbi dzisina tsvina, dzakaita se304 kana 316, zvinonetsa nekuda kwenzvimbo yadzo yekunyungudika uye tsika yekuumba nhanho dzakaoma, dzakaoma kana mwero wekutonhora ukasadzorwa. Uye alloys anokosha? Ndiro basa repamusoro-soro. Kudururira nickel-based alloy ye-high-tembiricha application kunoreva kudzora zvese kubva muchoto mhepo (kudzivirira oxidation yezvinhu zvinodhura senge chromium) kugadzira gedhi kuderedza mhirizhonga inogona kukanganisa mold yeceramic uye kusvibisa kunyungudika. Chinonyanya kukosha apa ruremekedzo. Haungodire izvi; iwe unoronga nhoroondo yavo yese yekupisa.
Kupfuura Kukandira: Iyo Machining Handshake
Kukanda hakuwanzo kuve chikamu chakapedzwa. Apa ndipo pane synergy panzvimbo yakadai QSY inoratidza kukosha kwayo. Kuva CNC machining mumba haisi nyore chete; chinhu chakakosha chemhinduro loop. Iwo machinists anotiudza chaizvo apo kukanda kwakaoma kana kupfava, uko kune kusingatarisirwe porosity, kana kana kushivirira kwedu kwakamira. Isu takagadzira bracket kamwe patakasiya zvataifunga kuti machining stock akawanda. Chikwata cheCNC chakadzoka ndokuti kukanda kwacho kwaive kukanganisa pasi pesimba rekucheka mune imwe chaiyo flange. Nyaya yacho? Residual stress kubva kutonhora kusina kuenzana. Isu takagadzirisa kutonhora kweprotocol munzvimbo ye shakeout, dambudziko rakagadziriswa. Chidzidzo chakakosha: kukanda hakupereri pakuzununguka. Yekutanga kucheka kwemuchina chishandiso ndiyo yekupedzisira yemhando bvunzo.
Uku kubatanidzwa kunoumba magadzirirwo atinoita mapatani uye mold. Isu tinoziva izvo michina yedu inogona uye isingakwanise kuita, saka isu tinogadzira macasting ane machinability akabikwa kubva pakutanga. Isu tinogona kuwedzera diki datum padhi pane isiri-yakakosha nzvimbo kungopa iyo CNC yakavimbika zero point. Icho chinhu chakakosha chaunodzidza chete nekuita mativi ese ebasa.
Kukundikana Ndiwo Mabhuku Chaivo
Rega ndipedzise nenyaya inoputira zvisizvo, zvisiri mutsara chokwadi che zvakakosha zvekukanda simbi. Isu takanga tine odha yeakatevedzana ekudzivirira-kuora mune duplex simbi isina tsvina. Iyo geometry yaive yakaoma, yakatetepa vanes, saka takaenda neinvestment casting. Vashoma vekutanga vakabuda netumwe tumisodzi twaive pavane. Kwete kutsemuka, asi kusarongeka kwepamusoro. Takatarisa zvese: wax jekiseni paramita, ceramic slurry viscosity, dewaxing autoclave kutenderera. Zvese zvaive mukati mekufungidzira.
Kubudirira kwakaitika apo mumwe mugadziri wechikuru, akanga akatarisa chinyararire, akanongedza pamhepo yainyura. Uri kubika wakisi nekukasira, akadaro. Chipfunga chiri kurova ganda rinotonhora, kunyungudika, uye mvura iri kuvharirwa munzvimbo dzepasi dzeforoma isati yadonha. Paunodira simbi yakanyungudutswa, mvura iyoyo inopenya kupfungaira pakarepo uye inofuridza kaburi kadiki-diki kumeso kweceramic, iyo simbi yacho inobva yazadza. Yakanga iri yakakosha nezve shanduko yechikamu uye condensation, kwete nezve casting per se. Takanonotsa nzira yekukwira, yakabvumira mvura iri nani, uye hurema hwakanyangarika. Chaicho chaicho chakanga chisiri musimbi; yakanga iri mumvura. Uye haungazviwani kunze kwekunge wakamira pasi, wakagumburwa, uchitarisa mutsetse wezvikamu zvakanakisa, zvisina kukwana. Ndiwo moyo wezvose.
